Pragmatic AI

Pragmatic AI is designed to solve well-defined problems, as opposed to being allowed to seek its own purpose.

Ethical AI

Ethical AI uses artificial intelligence to enhance the human condition by performing tasks that are menial or impractically slow to accomplish manually. Key factors in maintaining ethical AI include:

  • Explainability – the algorithms used can be understood by humans, with calculations that can be explained in plain language. This is essential to verifying that AI is serving its intended purpose.
  • Boundedness – Ethical AI is set to operate within pre-determined boundaries, and does not have the ability to create its own pathways to exploring or learning unintended information.
  • Purpose – Ethical AI is modeled to produce only specific answers to well-defined problems.

SMOTE

SMOTE stands for Synthetic Minority Over-sampling Technique. Oversampling is a technique used to manage class imbalance in data sets. Data set imbalance occurs when the category you are targeting is very rare in the population, or where the data might simply be difficult to collect. SMOTE is helpful when the class you want to analyze is under-represented.

SMOTE works by generating new instances from existing minority cases that you supply as input. SMOTE does not change the number of majority cases.

New instances are not just copies of existing minority class instances. SMOTE synthesizes new minority instances between existing (real) minority instances. The algorithm takes samples of the feature space for each target class and its nearest neighbors, and generates new examples combining the features of the target case with features of its neighbors. This approach increases the features available to each class and makes the samples more general.
